I update bios of my Lapbook Pro 4GB with this file “E.G140J.S4.E1.002.GLK_EC_G140J_V130806” from the official post ([Lapbook] [Official Version] Chuwi LapBook Pro Windows, BIOS, Drivers,Download)
Unfortunately, my lapbook became instable.
Can you upload the original bios for Lapbook Pro 4gb?
If you need information about my system ask me.
Thanks you.
